Nearly 2,000 passengers were trapped briefly when a glitch stalled a Metro train underground during the evening rush hour, which led to a cascading effect disrupting services in entire north Kolkata.

The Dum Dum-bound train from Girish Park, overcrowded because of the puja rush, came to a halt due to a glitch in the tunnel before entering Sobhabazar station and Metro Rail employees had to carry out an emergency evacuation of the 2000 passengers on board, Metro sources told PTI.

Angry passengers went on the rampage at the station and ransacked the ticket counter with the police making some arrests, the sources said.

As a result, services between Dum Dum in the north and Park Street in central Kolkata remained stalled since 6:30 pm. Metro services were normal up to Kavi Subhas station in the south.

The disruption of the services led to further trouble with passengers demonstrating at Metro stations.
